  • Specify FSC in project performance requirements!

  • Include Chain-of-Custody* documentation as a submittal requirement (*Unique to FSC in forest certification, chain of custody verifies that FSC-certified material has been identified and separated from non-certified material as it makes its way along the supply chain, from forest all the way through to final product. It provides assurance that the material originated from a well-managed forest.)

  • Don't assume - verify! Before sourcing building materials and other FSC products, visit to verify that companies have a valid certification. All organizations with valid FSC certifications are included in this database - if they're not listed or their certification is not currently showing as valid, they're not certified.

  • Require that that companies include an FSC claim on their purchase invoices. FSC claims must include the company's Chain-of-Custody Certificate Code, which is a unique identifier connected to each certified company. Use to make sure the CoC number given matches the actual company name associated with it. One company cannot use another's CoC number (such as using the CoC number of their vendor).
